MyDNS probably won't start properly if it can't find its configuration file. By default, the configuration file is called `/etc/mydns.conf'.
mydns --dump-config will output a set of configuration
options suitable for using as your configuration file. See section B. Configuration.
So, for a fresh installation, this command will create your initial configuration file:
# mydns --dump-config > /etc/mydns.conf
You should now edit your `mydns.conf' file. Most defaults should be fine for most sites.
The values you are most likely to want to modify are the values for `db-host' and `db-user', which should contain the database username and password that you created at the end of step 2.4. (See section 2.4 Database access).
